There are peaceful Muslims. So what?

Are peaceful people irrelevant? During a Heritage Foundation (conservative think tank) panel discussion about Benghazi, some poor Muslim girl tried to make the point that while some Muslims are radical, they are the minority. That set off this response

They are irrelevant. Because they let themselves be shouted down, among other reasons. The majority could turn on the radical minority, but they have no stomach for a fight. So, you see, it is largely due to wanting peace that the violent ones are given a relatively free hand.
